In 2021, 62% of the population was connected to the municipal wastewater treatment systems with secondary or tertiary treatment, which do not produce GHG emissions. Compared to the previous year, the share decreased by a small percentage point, moreover, the share has remained almost unchanged since 2017.

In 2021, the amount of incentives for the implementation of measures related to energy efficiency (EE) and renewable energy sources (RES) in non-ETS industry amounted to EUR 4.1 million, i.e. 30 % less than the previous year. In 2022, according to currently available data, the amount was further reduced to EUR 1.1 million.

Energy efficiency in industry has improved significantly over the period 2005–2022, with a 39% increase. The sectors that have contributed the most to this were production of paper, machinery and equipment, chemical industry and production of non-ferrous metals, while the production of steel and non-metallic mineral products have contributed the least.

F-gas emissions from leaks from stationary installations increased significantly in 2022 due to a significantly higher use of refilled refrigerants. This represented a significant deviation from the indicative target for reducing emissions from the use of F-gases under the EU F-gases Regulation. Compared to 2015, F-gas emissions from leaks were 17% lower in 2022, while, according to the F-gases Regulation, they should have been lower by 55%.

The performance of EU countries in the field of eco-innovations is monitored by a composite index that includes 12 indicators from five thematic areas. Slovenia is ranked as an average eco-innovation performer. The values of the indicator are gradually improving and show the progress of the eco-innovation index, but they still remain below the EU average. The target value for Slovenia has not been set.
